Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amino acids serve as substrates for protein synthesis and nitrogen balance; electrolytes maintain osmotic and acid-base balance.
TRAVASOL 8.5% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, tissue repair, and maintenance of nitrogen balance in patients unable to tolerate enteral nutrition.
1-2 g/kg/day (0.1-0.2 g/kg/hour) IV via central line as continuous infusion.
Intravenous administration as total parenteral nutrition: typical adult dose is 8.5% amino acid solution at 0.8-1.5 g protein/kg/day, infused continuously or cyclically.

The terminal elimination half-life of individual amino acids varies but is generally short (range 0.5–2 hours) due to rapid uptake and metabolism. Clinically, the half-life of infused amino acids is not a relevant parameter for dosing; rather, infusion rate is adjusted to maintain nitrogen balance.
Not applicable; constituent amino acids have individual half-lives (e.g., 0.5–2 hours for most L-amino acids) but overall elimination follows zero-order kinetics during continuous infusion. Clinically, infusion rate determines steady-state concentrations.
Amino acids are primarily metabolized to urea and other nitrogenous waste products, which are excreted renally (90-95% of total nitrogen excreted as urea). Unmetabolized amino acids in plasma are also filtered and reabsorbed by the kidneys; negligible amounts are excreted unchanged (<5%). Biliary/fecal excretion is minimal (<2%).
Renal elimination of nitrogenous waste products (urea, ammonia) derived from amino acid metabolism; biliary/fecal excretion negligible. In healthy adults, >90% of infused amino nitrogen is ultimately excreted as urea in urine.
